t whenever he wants but if he wont go outside it kinda defeats the perpose. i really have no idea why he is doing it. he is the alpha in our pack of dogs(we have 3 copper, luna(german shephard), and lola( our mix breed mutt) all of the others go outside with no issues except him. its come to the point where i have to put them all out , drag him out (which isnt easy since he weighs 150 lbs) put up
